IMPROVEMENT IN COOKING-STOVES.

Specification forming part of Letters Patent No. 112,425, dated March 7, 1871.

' To all whom it may concern:

. Be it-known that I, DAVID OUR'rIs, of Mishawaka, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in (looking-Stoves; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, and

to the letters of reference marked thereon,

which form a part of this specification.

The nature of my invention consists in a revolving oven, forming part of a cooking-stove, and also in revolving shelves in the oven of a cooking-stove, as will be hereinafter more fully set forth. i

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which+-' I Figure 1 is'a longitudinal vertical section of my oven, withthe shelves; Fig. 2, a side elevation of a stove on reduced scale.

A represents the rear end of the top plate of a cooking-stove, and B is the flue under the same, through which the smoke and heat pass on'their way to the stove-pipe. On the top plate A is formed a-box, G, with pot-holes on top, and also opening E for thestove-pipe, giving the stove a somewhat similar appearance to what are known as the step-stoves.

The box 0 is provided with a door, F, at each end, and through the box, from end to end, passes ,a cylinder or drum, D, which is open at both ends and formsthe oven. At each end of the box O, immediately inside of the doors F F, are formed circular collars a a, over d which the ends of the oven D are placed, and

upon which the oven revolves. The oven D may be revolved by various means, and I do notconfine myself to the means by which this In the drawing I have represented clockwork to revolve the oven, which, in this case, is provided with a eogged rim to gear with the wheels of the clock-work; but the oven may be revolved hyother means. For instance, the

smoke and heat passing around the same may be employed for that purpose.

A damper may be arranged so as to 0011- I bearings, and on said shafts are secured horizonta-l shelves or plates G G. One of the shelves or plates on each of the shafts dis provided around its circumference with cogs, which gear with a spiral, 6, formed on the inner side of the oven D, so that for each revolution of the oven the upright shafts, with their horizontal shelves or plates, will be revolved the distance of one of said cogs.

It is of course evident that I may arrange revolving shelves in a stationary oven if 'so desired, such shelves to be revolved by clockwork or other suitable means.

The advantages of my invention are readily seen. The oven revolving, all parts thereof must necessarily be heated alike, and the shelves revolving obviates the necessity of watchin g and turnin g the articles being roasted or baked in the oven.

Having thus fully described my invention, what I claim as new, and desire to secureby Letters Patent, is-

The revolving drum D, in combination with the interior revolving shelf or shelves, substantially for the purpose set forth.

In testimony that I claim the foregoing as my own I atfix my signature in the presence of two witnesses.

DAVID CURTIS.
